| (Amounts and numbers in thousands, except per-share data)

Incremental shares of 273,000, 421,000, and 415,000 for 2014, 2013, and 2012, respectively, were excluded from the computation of the diluted earnings per common shares due to their anti-dilutive effect. Potentially dilutive securities representing approximately 21,000, 63,000, and 80,000 shares of common stock for 2014, 2013, and 2012, respectively, were also excluded from the computation of diluted earnings per common share because their effect would have been anti-dilutive.
